[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is a detailed description of the present invention with reference to the attached drawings. Figure 1-5 , the present invention is further described in detail. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0027] The present invention provides a loading and unloading device for a bending center that cooperates with an automatic sheet metal production line. The loading and unloading device 600 is located between the pushing unit 500 and the bending unit 400 of the bending center, driving the bent sheet to move laterally, and includes a loading unit 100 and a unloading unit 200. The unloading unit 100 and the loading unit 200 are both provided with two relatively arranged conveyor belt assemblies 2. The conveyor belt assemblies drive the bent sheet to move, thereby realizing the loading and unloading of the bent sheet. The conveying directions of the unloading unit 100 and the loading unit 200 are consistent, ensuring loading at one end and unloading at the other end, and the production process proceeds in an orderly manner.

[0028] The two conveyor belt assemblies 2 are installed on the base frame 7 through the lifting assembly. A support assembly is provided at the center of the two conveyor belt assemblies 2. The support assembly is fixed on the base frame and does not affect the movement of the lifting assembly. The support assembly includes a support seat, and a support panel is provided on the support seat. Support brushes 1 are evenly provided on the support panel. The support brushes can provide support while reducing the friction force on the bent plate during the bending movement, thereby reducing the working difficulty of the pushing unit.

[0029] A clearance is left between the unloading unit 100 and the loading unit 200. The loading unit 200 is equipped with a push assembly 300, which includes a push plate 6. The push plate 6 moves in the same direction as the conveyor belt assembly 2 rotates. The push plate 6 is mounted on a slider 10 via a lift cylinder 9 and is located at the center of the supporting assembly of the loading unit 200. The slider 10 is mounted on a linear slide 11, which is mounted on a lift plate 8 of the lift assembly. The lift plate 8 is equipped with a push cylinder connected to the slider.

[0030] The pushing plate 6 is provided with a power-assisting plate at one end away from the loading unit 200. The power-assisting plate is vertically arranged at the upper end of the pushing plate 6. When the plate needs to be transferred, the power-assisting plate contacts the end of the plate, which can drive the plate to move and prevent stagnation in the gap, thereby ensuring the smooth transfer of small plates.

[0031] When the plate needs to be pushed, the pushing cylinder drives the pushing plate 6 to move horizontally to the appropriate position through the slider 10, and the rear lifting cylinder 9 rises to be flush with the plate. The pushing cylinder drives the pushing plate 6 to move, so that the power plate pushes the plate to move to the unloading unit, and the plate is transferred under the action of the unloading unit.

[0032] The lifting assembly includes a lifting plate 8 connected to the conveyor belt assembly. The bottom of the lifting plate 8 is connected to the lifting cylinder 4. The lifting cylinder 4 is installed on the base frame 7. A plurality of guide rods 5 are provided between the lifting plate 8 and the base frame 7 to ensure the vertical movement of the lifting plate.

[0033] During use, the conveyor belt assembly of the first conveying unit is first raised and higher than the brush of the supporting assembly under the action of the lifting assembly, driving the plate to move horizontally to the center position of the bending machine, and the conveyor belt assembly is lowered to below the brush. The aligning device in the bending center adjusts its position on the brush, and the pushing device drives the plate into the bending machine for bending. After the bending is completed, the conveyor belt assembly of the unloading unit is raised and higher than the brush, driving the plate to be unloaded. At this time, the pushing assembly also pushes the plate to move until the plate is driven by the conveyor belt to complete unloading.

[0034] The present invention realizes efficient and orderly loading and unloading of plates through the coordinated work of the unloading unit and the loading unit. Both units are equipped with a conveyor belt assembly to ensure the smooth movement of the plates during the bending process. The conveyor belt assembly is installed on the base frame through the lifting assembly, and the support assembly at the center is provided with a support brush, which not only supports the plates but also reduces friction and reduces the working difficulty of the pushing unit. The pushing assembly on the loading unit ensures that the plates will not stagnate in the gap. Through the coordinated action of the pushing cylinder and the lifting cylinder, the pushing plate and the power plate work together to achieve smooth transfer of the plates, thereby improving production efficiency and the stability of plate processing.
